Regarding GB50057-94 (Revised edition in 2000) Code for Design of Lightning Protection of Buildings

It’s perfect! Do you think there’s any problem? Question!

Please refer to clause 1.0.2: This specification does not apply to the lightning protection design of outdoor chemical processing equipment.

So far, this standard has been used for safety assessments. But what you said does make some sense as well.

If it is a petroleum facility, please refer to the Lightning Safety Code for Petroleum and Petroleum Facilities GB 15599-2009

I’ve always had a rather vague understanding of the concept of “open-air chemical processing units with frame structures”. Since even storage tank areas and stockyards are classified as “buildings” in building codes, then a frame structure can generally be considered a building as well, right? At the very least, it can be classified as a \"structure,\" so I never paid much attention to the fact that this outdoor chemical processing facility might not meet the requirements of lightning protection design standards; to be honest, I really didn’t pay any attention to it

Article 1.0.1 of GB50057-94 (revised in 2000), Code for Design of Lightning Protection of Buildings: This code is formulated to enable lightning protection measures to be adopted in a manner appropriate to the specific conditions of each building (including structures, the same hereafter) for the purpose of preventing or reducing casualties caused by lightning strikes on such buildings, as well as losses to cultural relics and property. It aims to ensure safety and reliability, as well as advanced technology and economic Reasonableness. Article 1.0.2 These specifications apply to the lightning protection design of new buildings. This specification does not apply to the lightning protection design of antenna towers, shared antenna television reception systems, oil tanks, and outdoor chemical processing equipment. It appears that the lightning protection design for antenna towers, shared antenna TV reception systems, oil tanks, and outdoor chemical processing equipment should not be based on this standard; instead, standards such as the Code for Fire Protection Design of Petrochemical Enterprises and the Code for Lightning Safety of Petroleum Facilities GB 15599-2009 should be used in these cases.

I find the concept a bit vague; GB50160-2008 requires that the lightning protection classification and measures for buildings and structures within process installations shall be carried out in accordance with the relevant provisions of the current **standard, the ‘Code for Design of Lightning Protection of Buildings’ GB50057. ” The Code for Design of Lightning Protection of Buildings GB50057 also stipulates that \"this code is not applicable to the lightning protection design of antenna towers, shared antenna television reception systems, oil tanks, and outdoor chemical equipment.\" ” I don’t understand what is meant by “structures and buildings for process equipment,” nor what the scope of “off-site chemical plant facilities” is. I think there must be an overlap between these two, but I’m not sure how that overlapping part should be designed. It’s quite troublesome. . . Looking forward to the answers from experts. In the lightning protection remediation work carried out by our company, the design institute also used 50057; I don’t understand why, haha

For chemical industry outdoor installations, it is recommended to first classify the areas as being at risk of explosion and fire in accordance with GB50058-92 \"Code for Design of Electrical Installations in Explosive and Flammable Environments\". After determining these areas at risk, the lightning protection classification of the building should be determined in accordance with Chapter 2 of GB50057 \"Code for Design of Lightning Protection of Buildings (2000 Edition)\\", so as to decide which type of lightning protection measures should be used – category 1, category 2, or category 3.

Reply to 8# *AOKING99: Structures and buildings in industrial facilities refer to things like refining workshops – the equipment inside such workshops constitutes the refining facilities, while the buildings outside them are simply buildings, right? Open-air storage tanks and towers are of course different!
